¾What is the multilayer film?The composite film which laminates PET, PA as the functional layer to give gasbarrier property, pinhole resistant, and so on and PE, PP as the sealant layer.

¾Situation of waste treatment of the multilayer film

Most of multilayer films have been being disposed of (incineration, orlandfill), as these cannot be recycled to materials with required strength.The mill ends of these multilayer films of 15,000 t/month (estimate value) aredischarged from printing factories in Japan.

¾ Utilization of these multilayer films as recycled material by commpatibilizationtechnology of different kinds of plastics.¾ Converting to economically advantageous sheet by achieving both compatibilization and molding to sheets from shredded flakes of mill end of multilayer films.

 Both sides of Eco (recycled) Trays arelaminated with virgin film in order to ensureadditional product safety.
